In Android, there is a versatile class called GridView which can display any custom designed cells. You provide it with a layout for each item, fill in the values - and voila - it's working.
All is well, until you try to add something interactive to the Grid cell - like a button - you come across an interesting effect.
If you add a onClick listener to both the GridView and the Button inside the GridView - only one will get the click event. And you won't guess which one :) (hint: it's the button)
So basically, you can have interactivity - but not paired with OnItemClick events of the Grid.
Bummer, right?
Wrong. This can be rather easily fixed, and the problem lays in the way Android handles focus resolution between parent and child Views. For ListView you can play with Focusability parameter which controls who reacts first, and on GridView, just the the Button's Focusable parameter to false - and it just works. It still gets the touch events which cause the click, but it doesn't interfere with the focus mechanics of the Grid.
You're welcome!
